I'm not sure I really understand your post but I'll give it a shot.
Just for curiousity reasons, what oil are you running??
The clutch cable may be stretched. It's hard to tell but if the cable is going bad then it will stretch little by little after every ride.
Another possibility is that you have worn frictions and springs. If the clutch has 'never been right' then I would go ahead and replace the plates, springs, the cable, and run Honda HP-80 oil in there.
